Step-by-step explanation:
these are composite functions : a function of a function of a value.
this can have many more "staging" levels.
in essence, we calculate the functional result of the innermost function (with the given value) first, use that functional result as input value for the next function to the left. use that functional result as input value for the next function to the left. ...
f(g(x)) means therefore we start with g(x).
g(f(x)) means we start with f(x).
that is all. it is really simple. and actuality fun (like a maze - remember e.g. computer games, where you walked through one door and excited through a totally different door ?).
f(g(0)) =
so, we need g(0) = 4 - 0² = 4
and now we calculate
f(4) = 7×4 + 6 = 28 + 6 = 34
therefore,
f(g(0) = 34
g(f(0)) =
so, we need f(0) = 7×0 + 6 = 6
and now we calculate
g(6) = 4 - 6² = 4 - 36 = -32
therefore,
g(f(0)) = -32
Answer: the z score is - 5.33
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the Z-score test result of 1300 points.
For x = 1300,
z = (1300 - 1700)/75 = - 400/75 =
- 5.33

Answer: i don't see the math problem?
Step-by-step explanation:
2(x+2)+2(3x)=180
8x+4=180
8x=176
X=22°
I hope this helps
